Estou tentando configurar um contêiner do Ubuntu openssh-serverpara que eu possa ssh nele a partir do host. Eu sei que não é a maneira padrão de fazer isso, mas eu realmente quero ter ssh.

Este é meuDockerfile

# Select base image
FROM ubuntu:16.04

# Set the current working directory
WORKDIR /home

# Update the system, download any packages essential for the project
RUN dpkg --add-architecture i386
RUN apt-get update && apt-get upgrade -y
RUN apt-get install -y git build-essential make gcc vim net-tools iputils-ping ca-certificates openssh-server libc6:i386 libstdc++6:i386

# Allow ssh root login
RUN echo "root:root" | chpasswd

# RUN rpl "PermitRootLogin prohibit-password" "PermitRootLogin yes" /etc/ssh/sshd_config
RUN sed -i 's/prohibit-password/yes/' /etc/ssh/sshd_config

RUN cat /etc/ssh/sshd_config
RUN mkdir /root/.ssh

RUN chown -R root:root /root/.ssh;chmod -R 700 /root/.ssh

RUN echo “StrictHostKeyChecking=no” >> /etc/ssh/ssh_config

RUN service ssh restart


# Open port 22 so linked containers can see it
EXPOSE 22

# Import any additional files into the environment (from the host)
ADD otherfile .

Eu começo o contêiner com, docker run -t -d -p 2222:22mas sempre que tento ssh nele, sempre acabo recebendo o erro ssh_exchange_identification: Connection closed by remote host:

➜ ssh -v -p 2222 root@localhost /bin/bash

Alguém sabe o que causa esse erro e como corrigi-lo?

Estou instalando o nó em uma caixa macOS Mojave limpa usando o Homebrew. Estou tentando definir o diretório de instalação do npm em um diretório de propriedade do usuário; o diretório toolsjá existe e pertence ao usuário:

npm config set prefix '/Users/giorgio/tools/npm_global'

E isso falha com esta mensagem. Alguém sabe o que está acontecendo?
